Title: Geometry/mesh volume scatter - Corona Scatter with extra D
Post by: Oltskul on 2012-10-24, 15:51:31

- Volume scetter function for geometry.

Simply fill mesh with scattered geometry.

IMO it would be very efficient, e.g. if you want to fill room with bambilion dust particles.

I iam curently using PFlow -> Mesher -> Render. Today i will try to create "volume sctter fake" using Voronoi cells.

Its really simple to fill a space with random instances, and I can do it immediately. The problem here is how to decide what is on "inside" (its doable, but not trivial to implement). If you would settle for now with scattering inside bounding box/bounding sphere, I can do it, otherwise, it will have to wait for a while.

As you said, you can do this with Particle Flow or max's "Scatter" compound object. In pflow you can set your container object to delete particles touching it to eliminate intersections. Probably you can also find a free script to do this for example on scriptspot.

But you needo to use mesher - bacause at this moment Corone does not support rendering particles..

Ive already used Pflow with Mesher, but IMO it is not very renderfriedly solution


OS.

OMG IMG

this is "mesh volume" or just  Box'n'sphere scatter?

Anyway! (http://maxarea.com/imgs/smilies/15.gif)


edit: and perfect solution to box or extrude volumes is just to randomize random Z Offset

just box for now

Awesome! but mesh volume is not implemented so far ;)
